Visionstar JD-2600

High Speed Ultraviolet Reading

The lens is held through the sensor and the display indicates the ultraviolet measurement on a progress bar, which the manufacturer describes as being high speed.

Thermal Printer Fitted

A thermal printer is listed on this model, described as giving quick data printing with easy reloading of the printing paper when a roll runs out.

Sphere, Cylinder and Add

Sphere reads 0 to plus or minus 25D, cylinder 0 to plus or minus 9.9D and add 0 to 9.99D, each selectable at 0.01, 0.12 or 0.25D resolution steps.

Automatic Lens Recognition

Single, progressive and automatic recognition modes are provided, so the instrument identifies a single or progressive lens without the operator declaring it.

Progressive Measurement Graph

A graph assists during progressive measurement, which the manufacturer relates to improved accuracy and speed across both near and far vision alike.

Tilting Touch Screen

The colour LCD tilts for a clear view whether the operator sits or stands, and a sensitive touch screen completes a measurement with recognisable icons shown.

Prism and Contact Lenses

Prism is presentable in X-Y or P-B form, cylinder as plus, plus and minus or minus, and both soft and hard contact lenses can be measured on the instrument.

Wide Acceptance and Light Weight

Lens diameter runs 20 to 108mm, pupillary distance reads 40 to 90mm in 0.5mm steps, measuring speed is 0.1s and the whole instrument weighs just 6kg altogether.

Verifying Ultraviolet Claims

This is where the ultraviolet function earns its place. Any practice dispensing lenses sold upon their protective properties can confirm at the bench what a given lens actually transmits, instead of merely passing on an assurance made further up the supply chain. Where a patient asks what their own lenses really do, a measured answer is a considerably better one than a claim simply repeated onward.

Progressive Lens Verification

Automatic recognition and the progressive graph together address the lens type that causes the most difficulty. Measuring a progressive lens in single vision mode will give a plausible wrong answer, and that error is easiest to make on a busy bench. An instrument that identifies the lens for itself removes a whole category of mistake from the routine verification work of a whole bench.

Tolerance Checks and Queries

A 0.01D resolution step settles a dispute definitively, where a quarter step would leave room for argument. Taken with the fitted printer, a practice can produce all the measured figures on paper at the moment a pair is questioned, which carries far more weight with a patient than a number recited from memory, or written up afterwards from somebody's recollection of it.

Optical Laboratories and Benches

A 0.1s measurement and acceptance from 20 to 108mm suit any bench working through volume, taking both the uncut blanks and finished lenses. At just 6kg the instrument moves between rooms without any difficulty, so a laboratory and a dispensing area can share one unit, with no need for each to justify a machine entirely of its own.

Coating Claims Become Measurements

Most lens properties can be checked upon any lensmeter, but ultraviolet transmission ordinarily cannot. Having it read as the lens passes the sensor turns a supplier's claim into something the practice has confirmed for itself. For anybody dispensing upon the strength of protective properties, that shift from mere assurance to actual measurement is worth rather more than any single figure among the measuring ranges themselves.

Evidence Produced at the Bench

A fitted printer means the figures exist upon paper the very moment they are taken, without depending on somebody remembering to write them all down afterwards. For a practice resolving a query about a pair of spectacles, a slip produced at the point of measurement carries considerably more weight with a patient than any number recited from memory, or copied out later on into a paper file somewhere.

The Instrument Knows the Lens

Automatic recognition removes a decision that the operator would otherwise have to get right every single time. A progressive lens measured in the wrong mode will return a figure that looks perfectly reasonable and yet is not correct, which is the most dangerous sort of error, because nothing about it ever prompts a second look from whoever happens to be reading the screen at that particular moment.

The Visionstar JD-2600 reads sphere from 0 to plus or minus 25D, cylinder from 0 to plus or minus 9.9D and add from 0 to 9.99D, each selectable at 0.01, 0.12 or 0.25D steps, with axis across 0 to 180 degrees. Lens diameter is accepted from 20 to 108mm, pupillary distance reads 40 to 90mm in 0.5mm steps, and measuring speed is 0.1s. Ultraviolet measurement is indicated on a progress bar as the lens passes the sensor, single, progressive and automatic recognition modes are provided with a graph assisting progressive work, and both soft and hard contact lenses are measured. A thermal printer and a 7 inch tilting touch screen are fitted, and the instrument weighs 6kg.

Two points need settling before an order. The published specification is identical to the other printing model on the same sheet, so what separates them is a question for Medigear.uk. And the prism row is labelled as prism degree with a dioptre unit, where prism is conventionally expressed in prism dioptres, so that notation wants clarifying. The electrical supply specification is not reproduced here.
